ABSTRACT OF THE DISCLOSURE A rubber stamp printing set comprises aplurality of rubber type blocks, means for holding a plurality of thetype blocks for printing and a case for the type blocks and holdingmeans. The type blocks are cubical with a raised printing character onthe bottom face, a preferably recessed identifying character on theupper face and slots in opposite side faces. The holding'means comprisesa slide bar having spaced tongues which engage in the slots in the typeblocks and a holder of channel cross section with grooves on inner facesof opposite side flanges to receive the tongues of the slide bar andthereby retain the type blocks. At least the top of the holder istransparent so that the identifying characters of the type blocks can beseen. Means is provided for securing a plurality of holders in assembledside-by-side relations. The case has a slotted plate engaging the slotsof the type blocks to to hold them in place and means cooperating withthe securing means on the holders to position them in the case.

The invention relates to a rubber stamp printing set comprising a casecontaining interchangeable elastic type which have printing characterson their bottom faces and legible identification characters on theirupper faces which can be seen when the type are set in a holder forprinting.

The stamp set in accordance with the invention is particularly suitablefor instruction, but can also be used in any oflice where there is aneed for rubber stamps with a text which is frequently changed so that astamp with fixed type is not Worthwhile. For good printing results it isdesirable for the type to be securely held in their holder and thatmoreover, for the stamp characters to be visible at all times includingduring stamping and in particular when selecting different previouslyprepared stamps. This is of particular importance in educational toys.In accordance with the invention, the continuous and complete visibilityof the characters does not interfere with satisfactory application ofpressure to the type during printing. In spite of these advantages, theholder and the further elements are of simple construction so that thestamp set can be produced and sold at a low price. There is alsoprovided a simple and orderly storing of the type. Moreover, the typecan easily be removed from the storage positions and inserted in theholder- The holder which encloses three sides of the type has at leastthe top portion transparent so that the type can be seen through it.Through the transparent construction of the holder, the legends whichare usually placed on the tops of the type blocks can be seen even whenthe type has been inserted in the holder. Moreover, the holder isfashioned as a grip so that it is not necessary to have the usual roundor long grip provided over the stamp. Because the elastic type areenclosed on three sides by the holder and on two further sides byneighboring type blocks, they can not be readily deformed. They arethereby retained in proper position during application of pressure onthe surface to be printed so that a very clean impression is obtained.In spite of this, the stamp identification characters are alwaysvisible.

Although the transparent portions for identification of the charactersof the type can be formed as small slits not impairing the support, itis particularly advantageous for the transparent portions to be formedof transparent plastic or the like so that substantially the entireupper face of the type is supported. The identifying characters can bemade as large as desired. The transparent portion is particularly easilyproduced when the entire holder is formed of transparent plasticmaterial.

In order to secure the type satisfactorily in the holder as well as tostore them in selected arrangement in the stamp case, a further featureof the invention is that the type are provided on opposite sides withslits that receive a double tongue slide-bar which is insertable in theholder and can be secured in place. The slide bar serves as a settingframe in which individual type are inserted to compose the type line.Moreover, by means of the slits, the type can be inserted in acorrespondingly slotted plate in the cage for storage in an orderlyarrangement.

An easily produced holder in which the type can be easily inserted andwhich provides a good grip consists advantageously of an elongatedhousingtof channel cross section, the underside and one end of which areopen. On the opposite inner side walls of the housing there arelongitudinally extending grooves, the width and depth of whichcorrespond to the portions of the tongues of the slide bar projectingbeyond the type. The slide bar carrying the type is inserted in thegrooves through the open end of the housing. In order to cover the openend of the housing and to facilitate insertion and removal of the type,the slide bar is preferably provided with an upwardly projecting tonguewhich preferably extends above the upper edge of the housing. The slidebar can be easily and economically produced as a steel or sheet metalstamping. Because of their low price, which is much less than that ofthe holders, a large number of slides can be provided with a set. Astamp having the desired text can be composed by assembling the requiredtype on a slide bar. The type can be left on the slide bar when it isdesired to use the holder for another stamp. It is hence unnecessary toremove and sort all of the type each time a new stamp is needed sincethe stamp text can be left on the slide bar. In order for the type toremain on the slide bar when inserted in and removed from a holder, theslots in the type are preferably formed so as to grip the tongues of theslide bar firmly while the type have a looser engagernent with the innerwalls of the holder. The securing of the type on the holder can also beattained or assisted by forming the tongues so that their free endsconverge. In order to secure the slide bar and assembled type in theholder, insofar as the elasticity and gripping of the type does notsuffice, the ends of the tongues extend into openings in the end wall atthe closed end of the holder and are preferably provided with notchesand teeth engaging corresponding portions of the holder.

In order that the transparency of the upper portion of the holderthrough which the identifying characters holder. It is then possible toassemble a plurality of holders next to one another and it is notnecessary to have a special holder for multiple-line printing. Anadvantageous and simple manner of providing means for connectingadjacent holders is to provide on the side walls of the holders pins andholes which are so arranged as to engage corresponding holes and pins onthe side wall of an adjacent holder. In the event one pin breaks, theremaining pins provide adequate means for securing the holders together.The pins and holes further assure that an individual holder can besecurely gripped during use.

Alternatively, a dove tail connection between adjacent holders can beobtained by providing a dove tail groove on one of the longitudinal sidewalls of the holder and a corresponding dove tail tongue on the other.The tongue and groove of adjacent holders interengage with one anotherto secure the holders together. While this provides a still betterconnection than the embodiment with pins and holes, it has thedisadvantage that upon breaking of the dove tail connection, the holderscan no longer be connected. The production of the connecting means isparticularly simple when the holder is molded of transparent plasticmaterial. The connecting means is produced during molding merely byproviding an appropriate die. Hence no special tools are required. Themeans for joining two or more holders can also advantageously be usedfor securing the holders in the stamp case merely by providingcorresponding interengaging means in the case to cooperate with theconnecting means on the holders.

In order to store the type in the stamp case, there is provided a platehaving a thickness corresponding to the slots provided in opposite sidesof the type and having storage slots in which the type can he slipped.Underlying the slotted plate, there is preferably a printed sheet havingprinted characters which appear through the slots to indicate thepositions in which corresponding type is to be stored. It is hencepossible to see at a glance whether all type having like letters are inthe case or whether some have been lost. So that it is not necessary toextend the storage slots to the edge of the plate, which would impairthe stability of the plate and require additional connections, thestorage slots in the plate are provided with wider portions so thatindividual type can be inserted through these enlargements.Advantageously several wider portions are provided in each of thestorage slots so that the distance the type have to be pushed along theslot is not great. However, with this arrangement there is the dangerthat, particularly when used by children, the type might not be arrangedin the correct place. For stamp sets to be used by children, a betterarrangement is to provide a wider portion at one end only of each slot.*It is then not necessary to provide an underlying printed sheet bearingindicia to identify the slots but sufiices merely to provide thecorresponding characters on the slotted plate adjacent the correspondingenlargements. Still other arrangements may be used to identify thestorage slots.

The stamp case may be in the form of a portfolio or in the form of amolded plastic case having a hinged cover. A slotted plate for storageof the type blocks by engagement with slots in the sides of the type canreadily be mounted in a stamp casing molded of plastic material byproviding in the side walls of the casing grooves to receive the slottedplate. The plate is spaced upwardly from the bottom of the casing toprovide space for receiving the lower portions of the type blocks. Inorder to save room, the slotted plate may be provided only in thatportion of the casing where it is desired to store type.

There is also preferably provided a pair of tweezers for taking the typeout of the casing and setting it in a'slide bar. The tweezers arepreferably provided on their holding end with offsets, the spacing ofwhich corresponds to the spacing between the inner portions of the slotsin the type. There is thus provided on the ends of the opposite legs ofthe tweezers, projections which can be in: sertedbetween the edges ofthe storage slots of the type casing'and engage opposite sides ofindividual type. The offset assist in guiding the type so that theelastic type do not jam in the slots of the slotted plate.

Although the identifying characters on the upper faces of the typeblocks can be printed'or raised, it is pa'rticularly advantageous tohave them recessed in the type block so that there is a limited surfacelost for the application of pressure by the holder. A simple printedcharacter is easily worn off and a raised character would interfere withuse of the entire surface of the type for applying pressure.

The stamp case 1 shown in FIG. 1 is of portfolio type and can suitablybe made of plastic film or sheet material by solvent or thermal welding.It has a left cover 2 the outer corners of which are provided withspacers 3 which prevent direct contact with the right cover 4. The innersurface 5 of the left cover 2 serves to receive training texts,instruction for use, and the like. The two covers 2 and 4 are connectedwith one another by a hinged or flexible back portion 3a.

In the upper portion of a plate 4a, on the inside of the right cover 4,there are provided rows of slots 6 which have spaced wider portions 7.The enlargements 7 of the slots 6 are wide enough to receive a typeblock 8 so that the lower portion of the type block can be insertedthrough the enlargement and slits 18 provided in the sides of the typeblock can be slid over the edges of the slots 6 to retain the type inthe slots. The plate 4a-is provided with any desired number of slotsandis suitably spaced from the cover 4 or arranged loose from the cover,for example by being attached only at one edge adjacent the back 3a. Ifdesired a plurality of plates 4a can be superimposed on one another inthe case. As see in FIG. 1, a sheet underlying the plate 4a is printedwith letters or other suitable characters 9 which are visible throughthe slots 6 and enlargements '7so as to indicate which-type are to beinserted in particular slots.

Below the slots 6, and as a possible variation, there are shown twoadjacent slots 6a each of which is provided with an enlargement 7a atits left end. Adjacent the en largements 7a there are letters orcharacters 9a to indicate which type are to be inserted in therespective slots.

In the lower portion of the right cover 4 of the case 1 there is'shown atype holder 10 which is provided with pins and holes adapted tointerfit-with corresponding holes and pins of like holders to position aplurality of holders in assembled relationship. The holder is shown inmore detail in FIGS. 11 to 13. The holder 10 is secured in place in thecase 1 by suitable means which are not shown in the drawing but mayconsist of mating holes and pins provided on the cover 4 or on the plate4a in which the slots 6, 6a are provided.

There is also shown in FIG. 1 a type holder 11 provided with dove tailedconnectiing means as illustrated in FIGS. 7 to 10. The holder 11 issecured in place inside the cover by dove tail clamps 13 provided on theinside of the cover or on the plate 411.

Any desired number of type holders can be provided in the cover. For thesake of clarity, the type holders are shown disproportionately large inrelation to the cover in FIG. 1. Moreover, slots and type holders can,if desired, be provided on the left cover 2 as well as on the rightcover 4. Alternatively, slots can be provided on one cover and typeholders on the other.

FIGS. 3 and 4 show a generally cube-form type block 8 formed of elasticrubber or plastic material. On its upper face 14, the type block isprovided with a deep impression 15 of the letter or other charactercarried by the type block, here shown as the letter E. The underside 16aof the block is provided with raised type 16 of the character that is tobe printed. Opposite side faces 17 are provided over the entire lengthof the type block 8 with slits 18.

In FIG. 5, there is shown a slide bar 19 formed, for example, of sheetmetal or plastic and provided with spaced longitudinally extendingtongues 20 forming a slot 21, the width of which corresponds to thedistance between the inner portions of the slits 18 of the type blocksso that the type blocks 8 can be slipped onto the slide bar 19 with thetongues 20 of the slide bar received in the slits 18 of the type blocks.The tongues 20 of the slide bar 19 are sufficiently wide to projectbeyond the sides of the type blocks and be received in grooves 33 on theinside of the holder 12 as illustrated in FIG. 7. The right ends of thetongues 20 are rounded to facilitate introducing the type blocks intothe slot 21 and inserting the slide bar 19 into the grooves 33 in theholder 12. The left end 22 of the slide bar 19 is closed and is providedwith an upwardly bent tongue 23. As seen in FIG. 7, the tongue 23projects up above the upper face 24 of the holder 13 so that it caneasily be grasped even when the slide bar is assembled with the holderand type blocks.

In FIG. 6, there is shown a holder 12 formed wholly from clear or atleast transparent plastic material and provided on its longitudinal sidewalls with concave, rubber gripping surfaces 25. The holder is formed asan elongated channel of generally rectangular cross section and theunderside 26 is provided with an opening 27. The left end 28 is alsoopen while the right end is closed by an end wall 44 having an upwardlyprojecting web 29 as seen in FIGS. 6 and 14 to 16. The side walls of theholder have upwardly projecting web portions 31 which extend up abovethe clear, or at least transparent, upper surface 30 so as to protect itfrom scratching that would interfere with its transparency.

The opposite inner faces 32 of the holder 12 are provided withlongitudinally extending grooves 33 to receive the tongues 20 of theslide bar 19 in the manner which is illustrated in FIG. 7, which showstype blocks assembled in a holder 11 of the kind illustrated in FIGS. 8to 10. The front ends of the grooves 33 'are preferably widened to formfunnel-shaped entrance portions to facilitate insertion of the slide bar19.

In FIG. 2, there are shown tweezers 34 having a gripping end 35 providedwith offsets 36 which between them form reduced portions 37 the width ofwhich corresponds to the width of the slot 21 of the slide bar 19 andthe slots 6, 6a of the case 1.

When it is desired to assemble a stamp, the operator takes a slide bar19 in one hand and the tweezers 34 in the other, guides the gripping end35 of the tweezers on opposite sides of the first letter desired on theright cover 4 of the case 1 and inserts the holding end of the tweezersuntil the offsets 36 engage the plate 4a, then presses the oppositeportions of the tweezers together and slides the selected letter to theadjacent enlargement 7 of the slot 6 and lifts it out. He then slidesthe letter onto the slide bar 19 so that the legible representation 15of the type block 8 faces uuwardly. When the slide bar 19 has beenprovided with the desired letters and with non-printing end and spacerblocks, the operator slides it in one of the holders 10, 11 or 12,removed from the cover 4, so that the type face 16 projects outwardly ofthe holder. The legible representations of the respective characters onthe upper faces of the type blocks are positioned under the upper face30 of the holder 10', 11 or 12.. As this is formed of clear ortransparent plastic and is smooth and blank, the legible characters onthe tops of the stamp blocks are clearly seen through it. The operatorholds the stamp by the longitudinal side faces and can use it like anyother, but the stamp text can be seen through the transparent surface 30so that any errors in the selection or positioning of the type blockscan be detected and it can be ascertained whether the correct word isbeing used.

As the type blocks fit closely between the inner walls 32 and lieclosely under the upper wall 38, they are supported by these walls whenprinting pressure is applied to the type. As the type blocks 8 are quiteelastic, they conform to the walls of the holder. The type blocks arethus supported on three faces by the holder and on two faces by adjacenttype or spacer blocks, so that distortion of the type by the printingpressure is avoided.

In FIGS. 8 to 16 like parts are designated by the same referencenumbers. In FIGS. 8 to 10, there is shown a type holder 11 provided onone longitudinal side wall 39 with a dove tail groove 40 extending thefull length of the holder and on the other side wall 41 with a dove tailtongue 42 which likewise extends the full length of the holder. Thetongue 41 is adapted to engage in a groove 40 of a further holder 11 sothat any desired number of holders can be assembled side-by-side.

In this and in the following examples illustrated, openings 43 are shownprovided in the end wall 44 of the holder to receive the ends of thetongues 20 of the slider 19. The tongues 20 can, if desired, be providedwith small notches or ribs on their side edges which engagecorresponding ribs or notches of the holder to secure the slide inassembled position.

FIGS. 11 to 13 illustrate a holder 10 which on its opposite side wallsis provided with pins 45 and holes 46. When two such holders areassembled side-by-side, the pins of one holder engage holes in the otherholder so as to position the holders in assembled relation. 'In theexample shown in the drawings, a pin and a hole are arranged in pairs.

FIGS. 14 to 16 show a holder 12 which has already been described inconnection with FIG. 6.

The tongues 20 of the slide bar 19 may converge slightly toward the openend of the slide bar, being made sufiiciently resilient to spring apartto receive the type blocks when they are inserted. The closeness of fitof the several parts may be selected as desired.

In FIG. 17, there is shown a stamp case comprising a one piece plastichousing having side walls 47, a bottom 48 and a hinge joint 49 forattachment of a hinged cover 50. The side wall 47 is provided with agroove 51 spaced from the bottom 48. A plate 52 set into the groove 51is provided with slots 6, 6a to receive type blocks 8, the underportions of which are accommodated in a space 53 below plate 52. Theplate 52 extends only over that portion of the housing which is to beused for storage of the type blocks 8.

An important advantage of the invention is that the elastic type arevery well supported for application to the Work with satisfactorypressure although the characters are at all times visible. The type arevery neat and easilv set in proper position. In the setting of the type,the sliding rubber faces are held relatively lightly so that there is nogreat frictional resistance. Through the proper use of the tweezers,this can be still further reduced. The stamp text can be assembledbefore hand on a cheap slide bar and put into a holder only for theprinting operation. Even after the type has been introduced into aholder, the characters are readily recognizable and are not obscured byportions of the holder. The setting slide is simple and inexpensive toproduce and serves also to anchor the type in the holder. The slide isnot very large and hence takes only a small amount of room when it isdesired to provide a large number of slides in a portfolio or case. Thetype are elastically held without the need of additional springs. Theholder consists of only one piece and is very easy to produce by variousplastic molding techniques in particular injection molding.

It will be understood that the various features of the embodimentsherein shown and described by way of example, are mutuallyinterchangeable and that other modifications may be made.
